Electric butterfly valve has simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and fast operation, and also has good flow adjustment function and closing sealing characteristics. It is one of the fastest developing valve varieties in recent years. Especially in industrialized developed countries such as the United States, Japan, Germany, France, and Italy, butterfly valves are widely used. The variety and quantity of its use are still expanding, and it is developing in the direction of high temperature, high pressure, large diameter, high sealing, long life, excellent adjustment characteristics and multi-function of one valve, and its reliability and other performance indicators are high. level, and has partially replaced globe valves, gate valves and ball valves. With the advancement of electric butterfly valve technology, butterfly valve will become the dominant valve form. Electric butterfly valve is a kind of motorised valve and electric regulating valve. The electric actuated butterfly valve price is reasonable, and the cost performance is very high.
The electric butterfly valve controls the switch of the butterfly valve through the power signal. The product can be used as a shut-off valve, control valve and check valve in piping systems. By the way, the device is manually controlled. Once a power problem occurs, manual operation can be used temporarily without affecting the use.
1) With the development of motorised valves, there are many well-known valve companies at home and abroad producing motorised valves. Electric butterfly valves are an important execution unit in the field of industrial automation control. It belongs to a variety of motorised valve and electric regulating valve. It is widely used in textile, power station, petrochemical, heating and cooling, pharmaceutical, shipbuilding, metallurgy, light industry, environmental protection and other fields. The product can be used as a shut-off valve, control valve and check valve in the pipeline system.
2) The butterfly valve is complete with manual control equipment, electric or pneumatic transmission equipment, which can meet the specific conditions of different working conditions. It meets the strictest quality requirements and can be used for a long time. Especially in the metallurgical steel and shipbuilding industries, it has a very high reputation.
Because the pressure loss of the electric butterfly valve in the pipeline is relatively large, which is about three times that of the gate valve, when selecting the butterfly valve, the influence of the pipeline system by the pressure loss should be fully considered, and the consolidation of the butterfly plate receiving the pipeline medium pressure during closing shall also should be considered.
